《轴对称图形》是苏教版修订教材三年级上册第83页到第86页的内容,是一节实验课。教学中很多老师怕上这一类的课,一方面在于这类课课前需要准备的教具、学具较多,另一方面担心课堂的掌控到不到位,学生会不会和你预设的一样等问题。正当我也在思考这一类的课堂该怎么上的时候,恰巧翻阅到有一期《小学数学教学设计》杂志时,有幸看到了其中有位教师正好提出了高效的课堂教学追求“六性”:(一)学习过程需追求主动性;(二)信息交流需追求互动性;(三)知识获取需追求实践性;(四)掌握知识需追求理解性;(五) “Axisymmetric graphics” is a revision of the Soviet version of the third grade books on the first 83 to 86 pages, is an experimental class. Many teachers in teaching afraid of this type of class, on the one hand is that such lessons need to prepare the teaching aids, learning more, on the other hand worried about the classroom control is not in place, the students will not be the same as your default And other issues. Just as I was thinking about what was going on in this type of classroom, when I happened to read through the issue of “Primary Mathematics Teaching Design” magazine, I was fortunate to see that one of the teachers just came up with an efficient classroom teaching pursuit. "(1) the learning process requires the pursuit of initiative; (2) the exchange of information requires the pursuit of interactivity; (3) the acquisition of knowledge requires the pursuit of practicality; (4) the mastery of knowledge requires the pursuit of understanding; (5)
